Description

DETAILED DESCRIPTION OF THE INVENTION The present invention comprises a frame movable along the individual oven chambers of a coke oven, a control stand movable on the frame in a transverse direction perpendicular to the direction of frame travel; A coke oven operating device comprising a jib mounted on a control stand and controllable from the control stand, wherein the control stand is arranged on a turntable, and the turntable is arranged along with the jib along the turntable axis. The jib is rotatable about an axis perpendicular to the turntable axis, and the jib has a coolant passage and a free end of the jib has a cooling medium passage for each furnace chamber. The present invention relates to a type having a connecting head for a plurality of working devices, including at least a combined device consisting of a shovel and a scraper for removing coke from a workpiece.

The invention particularly relates to such coke oven operating steps that must be performed in modern horizontal chamber furnaces in addition to the scheduled coal feeding and coke discharge of the furnace chamber. The recent horizontal chamber furnace is about 8 chamber height.
This refers to a large-capacity furnace with a chamber height of approximately 16 m and a volume of 35 to 40 tons, but in the present invention, furnaces with dimensions of approximately 4 m in chamber height and 11 m in chamber length are also considered. In large-volume furnaces, particularly large forces are introduced from the coke extruder into the chamber charge, and during extrusion of the chamber charge, i.e., calcined coke, these forces are applied to the chamber walls of large-volume furnaces more than to the chamber walls of small-volume furnaces. Apply a strong load. Based on this,
The front top, furnace anchor braces, chamber walls and furnace chamber closing devices require intensive maintenance work, especially in large-volume furnaces, and this maintenance work is naturally necessary for the service life and therefore economic efficiency of the coke oven equipment. It is. In addition, constant monitoring of the furnace chamber walls, furnace top and furnace bottom is carried out in order to recognize and eliminate damage at the appropriate time, as well as to detect any graphite deposits on the furnace chamber walls in the area of charging holes, riser inlets and riser pipes. It is necessary to remove the kimono in a timely manner. This is because such graphite deposits, if not removed at the proper time, will cause significant operational trouble.

Furthermore, in the case of variations in the quality of the charged coal, abnormal operating conditions such as failure of the heating equipment, or failure of airtightness in the chamber frame and furnace chamber closing device, coke extrusion becomes difficult and coke cake Sticking may occur, and in this case, damage to the furnace wall due to lateral pressure cannot be avoided.

Also, if the coke extrusion process has to be interrupted midway due to the reasons mentioned above, damage to the mechanical equipment, chamber frame and braces may occur.
Part of the hot coke then becomes stuck in the coke transfer trough and has to be removed manually under difficult conditions. In such cases, the residual coke remaining in the furnace chamber is removed from the furnace chamber using a rod or a scraper to the extent that the remaining coke can be pushed out of the furnace chamber by a coke extruder. In extreme cases it may be necessary to empty the entire furnace chamber.

It is no longer acceptable to expect the physical exertion of operators associated with maintenance work (especially when a failure occurs). Moreover, the risk of accidents caused by scorching coke lumps falling from a height is extremely high. Despite the fact that almost complete mechanical operation of coke ovens corresponding to the high technical level of coke oven construction has been in place for quite some time, the work during the aforementioned operational troubles has never been matched. We have not yet reached the level where we can.

A device for removing coke from a furnace chamber is already known from German Patent No. 807,091, which aims to reduce the manual effort required to scrape out the coke cake stuck in the furnace chamber from the coke side. For this purpose, a gate-shaped structure is provided which can run on a track, the rails of which are laid next to the coke extinguisher track on an inspection path and on special foundations. The upper part of the gantry is used to support a scraper belt device which can be shifted into the furnace chamber and which can be pivoted vertically. The movable belt section of the scraper belt device is equipped with a plurality of shovels for scraping coke from the furnace chamber. A short belt conveyor is disposed on the movable belt portion as a conveying means, and the belt conveyor receives the scraped coke and carries it into the fire extinguishing engine. must be on standby.

Conventional coke oven operating equipment does not adequately take into account the practical requirements that must be kept in mind when coke cake becomes stuck in the oven chamber. In other words, the known device can only process the coke cake stuck to the coke side, and furthermore, the shovel of the scraper belt device may damage the bottom of the furnace, so the fixed coke on the bottom can only be left as is. I can't process it. This is because on the extruder side, because of the pusher beam of the extruder, it is not possible to level out the fixed coke cake horizontally, so the coke must be removed again due to the inclination of the pusher beam and the locking of the pusher transmission device caused by this. Even if you try to extrude it, it has the disadvantage that it doesn't work. Furthermore, if the bottom of the furnace on the coke side is not removed, there is a risk that the coke cake will become stuck in the furnace chamber again as the extrusion operation is repeated. Moreover, the heat of the coke cake puts a load on the coke oven operation itself and the coke guide wheel during the entire working time required to remove the operating shock of the oven, and as the operational disturbance increases, the damage to said equipment becomes more significant. Of course, it must be expected that this will happen.

When the frequency of operating problems in a coke oven becomes extremely high, coke cake becomes stuck not only inside the oven chamber but also inside the coke guide car. This condition is particularly serious in coke guided vehicles. That is,
This is because the coke begins to burn due to the oxygen in the air and the heat, and the coke guide wheel will be damaged in a short period of time due to the thermal effects. The scraper belt device of the known coke oven operating device is
First, it is assumed that the coke guide car is moved to the side. However, this lateral movement
This is only possible if the stuck coke cake can be torn apart as it moves. However, this tearing is often not possible because the drive power of the coke guide wheel is too weak. In this case, the hot coke is not only located in the coke guide car, but also falls between the anchor strut and the running mechanism of the coke oven operating device. This causes additional damage to the inspection aisle sheathing and anchor struts. Even if the coke guide car can run, the hot coke must be manually removed from the coke guide car. This operation is dangerous and cannot be carried out in a sufficiently short time. Damage to coke oven operating equipment is therefore generally unavoidable.

The coke oven operating device, which is known based on West German Patent No. 1101356, which is the starting point of the present invention, is capable of not only removing coke stuck in the oven chamber, but also performing injection, grinding, welding, etc. It does not help much, since it also takes into account the work equipment for carrying out the maintenance work. The frame of the coke oven operating device can run on the inspection path on the coke side and can be fastened to the anchor strut.
The frame has additional frame supports that support the work platform formed by the frame of the frame in the inspection path section. A combined device consisting of a shovel and a scraper serves as a loader and can remove coke stuck to the bottom of the furnace from the coke side. This known device is not very suitable for eliminating the above-mentioned operational troubles of coke ovens. This is because the treatment of the coke cake in the furnace chamber from the extruder side is almost impossible, as is the risk-free removal of the scorching coke discharged from the furnace chamber. Although this known device is travelable, for this purpose it is necessary to use a test path, which has certain limitations in order to absorb static and dynamic loads by such a device. Suitable only within range. Similar doubts arise regarding the use of anchor braces to secure coke oven operating equipment.

The object of the invention is to improve a coke oven operating device of the type mentioned at the outset so that coke cake can be processed from both sides of the oven chamber, in short from the extruder side and from the coke side, and which also The purpose of the present invention is to make it possible to remove coke carried out from a plant without danger.

The structural means of the present invention for solving the above problem is such that the frame is configured as a portal frame, and the portal frame is provided with controllable and individually driven traveling mechanisms on its four vertical columns, Each traveling mechanism is supported by a switch sleeper disposed at the lower end of the column and having a rotation axis perpendicular to the device axis, and is constituted by trackless driving wheels, and further includes the gate. The structure has a coke extinguishing system with an adjustable coke transfer conveyor reaching the bottom of each furnace, as well as a receiving device with a discharge conveyor.

Due to the configuration means of the present invention, the frame of the coke oven operating device of the present invention can be arranged on both sides of the coke oven bank, even though the trajectory of the coke extruder track is significantly different from the running track of the coke extinguishing truck. This makes it possible to travel in a trackless manner on the rail area of the track. This allows coke oven operating equipment to be used on each side of the coke oven bank as required. In particular, in order to eliminate operational troubles, the combined shovel and scraper device can also be used to create a suitable working surface for the pusher beam on the coke cake stuck in the furnace chamber. Since the coke oven operating device further includes a device for taking and processing the calcined coke in order to eliminate operational troubles, it is possible to immediately resume normal operation of the oven after eliminating operational troubles.

The novel coke oven operating device of the present invention utilizes conventional coke oven operating devices such as pressurized air injectors and mechanical scrapers, particularly in the form of rods and air lances, to scrape out calcined coke and remove graphite deposits from all over the bottom of the oven. Instead of the removal equipment, it becomes possible to work with a jib device tool that allows the required work steps to be carried out mechanically from the control stand. As a result, the thermal effects on the operator that have been associated with these operations and the generation of falling graphite shell pieces and strong sparks hinder manual operations, and large-capacity furnaces make such manual operations difficult to perform. The risk of an accident that would make it impossible can be avoided.

Based on its self-propelled mobility, the coke oven operating device of the present invention can be operated at the optimum position for each necessary work process on the extruder side and coke side of the coke oven bank, regardless of the energy supply network. can be occupied, in which case the stance stability of the device is not impaired. The jib of the coke oven operating device can therefore be used as a support for the collection platform, thereby making it possible to secure the coke oven bank lateral anchors, the oven chamber frame and the oven chamber closure within the framework of constant care and maintenance work. It is possible to avoid expensive moving and securing means of the work floor, which would normally have to be used for checking and adjusting the equipment.
It is also possible to use the jib like a lifting device.

In an advantageous embodiment of the invention, the portal structure has a platform on its upper part, on which the rails of the force-guided carriage are laid, on which the turntable,
The swing drive of the jib and the cockpit surrounding the control stand are supported, and below the platform there is an intermediate floor for supporting the water-filled coke collection vessel of the coke extinguishing system. The coke collection container is provided in a gate-shaped frame, and the coke collection container has a suction hood, the suction hood is provided with a dust removal device, and a coke delivery device that can be advanced into the coke collection container is provided. A conveyor is intruding, and an output conveyor is located below the coke collection vessel.

In the present invention, in order to eliminate operational troubles when extruding coke from the furnace chamber (details will be explained later),
In the various work processes, the scorching coke scraped out by the work can be received under the jib and extinguished at the same time, making it possible to carry out the coke without danger. Through the use of jibs it is possible to reach each half of the furnace chamber (including the furnace walls) from both the coke side and the extruder side, in which case the movements of the working equipment on the portal structure and The movements of the jib on the turntable are utilized or combined with each other.

In an advantageous embodiment of the invention, a swivel drive acting on the jib and a horizontally arranged actuating joint are arranged on the turntable of the control stand, the actuating joint being connected to the coolant inlet path and the coolant inlet. It carries a jib consisting of a plurality of jib sections with internal return passages, said jib near the working joint of said swivel drive being attachable to a connecting head via another horizontally arranged joint. , a drive for supplying kinetic energy to a power tool, such as a combined shovel and scraper, is fixed.

With the aid of a simple thrusting movement, it is possible according to the invention to use the component of the power tool both as a shovel and as a scraper. The shovel serves to receive the coke from the hearth bottom and avoid scraping it through the hearth as was previously the case. This protects the bottom of the furnace and the lower part of the furnace wall from damage. For particularly persistent coke, it is possible to equip the jib with claws or spikes. The jib and the connecting rod or driving rod installed on the jib to operate the shovel are constantly cooled by a forced circulation system connected to the cooling device, so the function and properties of the device are not impaired. . As a result, the operating time of the device according to the invention as well as the working time required for the individual working steps are significantly reduced.

Next, embodiments of the present invention will be explained in detail based on the drawings.

According to FIGS. 1 and 4, 1 is a furnace chamber, 2 is a furnace top, 3 is a furnace bottom, 4 is an inlet of a riser pipe, and 5 is a charging hole. In FIG. 1, the inspection passage 7 is shown on the coke side of the furnace bank. As can be seen from the plan view of FIG. 2, each furnace chamber 1 has a backstay 8 and a chamber frame 9. 10 is a heating wall.

Beneath the inspection passage 7 on the coke side of the furnace group, there is a rail 1 on which a coke extinguishing truck (not shown) runs.
A track 14 consisting of 2,13 is laid on the foundation 11. Between the rails 12 and 13 runs a coke oven operating device 15, which will be explained in detail below.

The device 15 has a carriage formed by a gantry 16 having vertical columns 17-20 and a plurality of diagonal stays, said diagonal stays being designated 22 and 23 in FIG. has been done. Swivel sleepers support each column of the portal frame 16.
sleeper) 24 supports a traveling mechanism 25 so as to be pivotable about a vertical axis of rotation. In the illustrated embodiment, each traveling mechanism is constituted by a plurality of wheels 26 and 27 with rubber tires. The traveling mechanisms are constructed identically. Wheels 2 of the traveling mechanism 25
6, 27 are driven by a hydraulic motor 28, which is supplied with pressure via a diesel-hydraulic drive (not shown), which drive is housed on the portal frame 16. There is. Each running mechanism 25 has an extendable support 2 with a suitable bottom plate 30.
9 are arranged. As a result, as soon as the coke oven operating device 15 reaches its proper working position, it is possible to reliably support the coke oven operating device 15 and to reduce the load on the wheels 26, 27.

For example, the portal structure 16 is provided with ramps at portions 31 and 32, and the ramps are connected to the intermediate floor 3.
3 or to connect the intermediate floor 33 with the platform 34. The intermediate floor 33 and the platform 34 have a handrail for disaster prevention, such as the one indicated by the reference numeral 35, for example. The portal structure 16 is also constructed in such a way that it can be fitted with protection against thermal effects and water vapor.

On the lower side of the upper surface of the platform 34, rails 37, 38 are laid which form a running track for a carriage 39 that is forcibly guided. The carriage 39 supports a fixed part of a turntable 40, the rotary part of which is rotatable about a vertical axis, to which is attached a cockpit 41 surrounding a control stand 42. A seat 43 for an operator is installed in front of the machine. The carriage 39 is moved in the direction of the double arrow 44,
Therefore, it is possible to move in the direction of the furnace center axis. The turntable 40 allows rotation of the cockpit in a horizontal plane. This rotation is used to operate the jib 45, which is connected to the carriage end 4.
At 6, it is supported in an actuating joint 47 having a horizontal axis of rotation. The jib 45 can also be pivoted in a vertical plane by means of a pivoting drive formed by one or more reciprocating piston devices 48, one end of which is mounted on the turntable. At the pivot point 49, and the other end is the jib 4
It is supported by a pivot point 50 provided on the lower surface of 5.

Said jib 45 is of three-part construction in the illustrated embodiment, thus consisting of an intermediate jib, a base jib 40' and an end jib 46'' which can be inserted into said base jib.The jib 45 is of hollow construction. Ori,
Further, as shown in FIG. 3, it has a cooling medium outward path indicated by arrows 95 and 96 and a cooling medium return path indicated by arrows 97 and 98. The cooling medium consists of water;
The water is supplied to the base jib 46' via an inlet connection 51 and led out of the base jib 46' via an outlet connection 52, as indicated by arrows 53,54. A schematically illustrated plug-in device 55 is used for connecting the base, intermediate and terminal jibs to one another and, via suitable connecting fittings 56, 57, to communicate the connected terminal jibs 46'' with the coolant flow path. useful for.

The end section 58 of the jib 45, located at the free end of the distal jib 46'', is bent upwards and supports a mounting head 59 for the shovel scraper device, for the work floor, and possibly for the steering grip. 1 shows the shovel and scraper device 60 mounted on the jib 45. The shovel joint 61 is connected to the mounting head 59. The shovel and scraper device 60 is a reciprocating piston. Actuated by a device 63 via a connecting rod 62, said reciprocating piston device is mounted on said base jib 46' in such a way that it remains outside the furnace chamber 1 when the carriage 39 is in its forward end position. It is pivotally supported on a provided bracket 64.

Below the platform 34, the hearth bottom 3
An intermediate conveyor 66 is arranged with an output chute 67 that can be attached to. The intermediate conveyor 66
Cover 6 for heat insulation, dustproofing and radiation prevention
8 and can be retracted into the portal structure 16 so as to move the coke oven operating device 15 along the oven bank without colliding with the inspection passage 7. Incidentally, the intermediate conveyor 66 is for conveying the scorching coke coming out of the furnace chamber 1 into a coke collection container 70 supported within the portal structure 16. The nozzle device 71 is for suppressing dust, mist, and steam that rise when scorching coke is introduced into the water-filled portion 72 of the coke collection vessel 70 . Since the walls of the coke collection vessel 70 converge downward, the coke can automatically fall onto the rear part of the discharge conveyor 74 for discharging the extinguished coke at a suitable location. The discharge conveyor 74 is driven by a drive device 75 (FIG. 2). On the intermediate floor 33,
As shown in FIG. 4, a water storage tank 76 for circulating a cooling medium and a cooling device 79 for cooling the circulating cooling medium are provided. Also, intermediate floor 3
3, there are installed a compressor, a hydraulic station, a generator, a pump station, a fuel tank for the diesel engine, a slurry tank, and a cooling system for compressed air and pressure oil.

The jib 45 is also used to attach a supply conduit, shown at 77 in FIG. 3, and to lower tools to the platform area, shown at 78 in FIG. 2, as will be described in more detail below. It is also possible.

According to FIG. 5, at the schematically illustrated end of the jib 80,
a plate 8 arranged at right angles to the jib 80;
A rotation joint 82 is fixed to 1. The joint pins 83 of the rotation joint 82 each have one
It is located almost at the apex of the two triangular bracket plates 84, and the bottom side 8 of the bracket plate 84 is
5 is connected to another plate 86. Said plate 86 has a cutting edge 87 as the edge of the front part and
The plate section 88 between 1 and the cutting edge 87 serves as a shovel, as can be seen from the shovel charge 89 schematically shown in FIG. plate 8
The plate rear section between the trailing edge 90 of 6 and the plate 81 acts as a scraper in the position indicated by the dashed line 91. The kinetic energy required for this is provided by the connecting rod 93, which itself is connected via a rotating joint 94 to the bracket plate 84.
is connected to.

Next, the individual functions of the coke oven operating device will be explained.

(1) Removal of operational problems caused by baked coke stuck in the furnace chamber If the baked coke in the coke oven is stuck and the scorching coke is still not transferred into the transfer trough of the coke guide car, first the coke guide car is moved to the side. . Next, the coke oven operating device 1
5 is moved to the front of the furnace chamber 1 and positioned correctly. Immediately after positioning, the support 2
9 is extruded, thereby stabilizing the coke oven operating device 15. All operations necessary to remove hot coke from the furnace chamber are controlled from control stunt 42. The machine operator is then not exposed to any danger from falling red-hot coke, thermal effects or emissions (fugitive dust or gases). The coke scraped by the shovel scraper device 60 reaches the extinguishing device via an intermediate conveyor 66 and from there to the coke collection vessel section.
The extinguished coke can be discharged into a container car (not shown) by an output conveyor 74. Gaseous and dusty emissions are rendered harmless via a suction device combined with a dedusting device. The suction device is connected, in particular, to a connecting piece 99 on the cover hood 100 of the coke collection vessel 70.

The shovel and scraper device 60 can carry out a simple thrusting movement, in which case it serves both as a shovel and as a scraper device.

As a shovel, the shovel and scraper device 60 receives coke from the furnace bottom 3 and empties it onto an intermediate conveyor 66. The static stresses are then absorbed by the strut system. This ensures the stability of the gantry 16 even at maximum jib lengths. The movement of the shovel scraper device 60 is supplemented by the movement of the carriage 39, which can be moved via a capstan device 92 (FIG. 2) with a deflection guide device. If such a capstan device 92 is used, it becomes possible to pull or push the carriage 39 with maximum force regardless of rail friction.

(2) Operation failure due to baked coke partially stuck in the furnace chamber and partially stuck in the coke guide car. The coke oven operating device 15 is immediately and intentionally used in the event of such an operation failure. In each case, the coke oven coke guide car remains at a position in front of the oven. The necessary operations take place from the control stand 42 of the coke oven operating device 15, first of all only the hot coke being removed from the coke guide. After this removal, the coke guide car can be moved to the side without any hindrance. Removal of the burning coke from the furnace chamber 1 is carried out in the same manner as described in the previous section (1).

(3) Sticky charge in the furnace chamber A situation may arise in which the charge in the furnace chamber must be scraped out from the extruder side (Figure 4). If the coke extrusion process is interrupted due to furnace operating problems, scraping of the furnace charge is almost always necessary. The reason is that in such cases the top of the coke cake is damaged. A new extrusion process can only be restarted once the loosened coke has been sufficiently removed from the furnace chamber so that the ram head can be brought into frictional contact with the coarse cake.

In large-volume furnaces, this operation can only be carried out manually and with great effort, since in such cases the coke cake is usually already too widely stuck in the furnace chamber. On the other hand, the coke handling device 15 can extremely simply and quickly level the coke cake to the extent that the extrusion process can be restarted using the necessary equipment that can be adapted to the operating conditions in each case (see Fig. 4). reference).

(4) Repair of ceramic materials To ensure trouble-free extrusion operations,
Regular maintenance of the ceramic parts of the furnace is essential. This maintenance work is generally performed manually.
Repairs are often not very durable. This is because the repair material can only be applied incompletely and very quickly depending on the location of the area requiring repair.

The coke oven operating device 15 has its jib 45,
It can be used to attach repair tools and at the same time fix the repaired area. Therefore, regardless of the location of the repaired part, it is possible to carry out the repair quickly and with durability as expected with a minimum number of personnel and repair materials. Control of the repair process takes place from a control stand 42, in which case the aiming of the damaged area can be carried out in a program-controlled manner using optical sensors or laser devices, and in combination with a microprocessor. A complete repair program including convertible tools consists of, for example, the following operating steps:

(b) Protection of the furnace head by spraying material compound (b) Leveling of the repaired area using a doctor blade or cutting device (c) Welding of damaged refractory brick surfaces and open joints of refractory bricks (d) Furnace bottom Application of the material compound and insertion of individual bricks into the wall joints (5) Optical monitoring of the furnace walls, furnace top and hearth bottom Specified times for regular checks of the furnace walls, furnace top and hearth bottom Optical monitoring is required at intervals. The optical monitoring is performed by examining and evaluating color grades from the extruder side and the coke side. However, such monitoring methods have not achieved remarkable results.

By using the coke oven operating device 15 of the present invention, which can use the end jib 46'' for mounting a television camera or an infrared camera, the oven wall and
It becomes possible to perform the desired inspection of the furnace top and hearth bottom. Damage can be recognized very quickly and repairs can be carried out in good time, increasing the usability of the coke oven and extending its service life.

(6) Separation of graphitic deposits in the furnace chamber, riser pipe, and charging hole as expected. Highly volatile coal is used, overheating occurs in the air collection chamber, the height of the furnace chamber is not optimal, and firing If the time is short, the formation of graphitic deposits in the area of the collection chamber, the riser inlet, the riser and the charging hole is unavoidable. These deposits become hard like stones after a certain period of time and are extremely difficult to remove.

All devices conventionally mounted on coke extruder ram heads, such as air sprays and scrapers, have not produced satisfactory results. Mechanical devices for removing deposits in charging holes and risers also do not work satisfactorily. Until now, it has been impossible to manually remove such deposits unless the degree of adhesion reaches a certain degree.

With the coke oven operating device 15 of the present invention, the removal of deposits from the control stand 42 can be carried out quickly and without danger by means of an impact cracker or an air lance mounted on the jib 45.
It can be done from This applies in particular to the removal of deposits deposited in the area of the riser inlet or in the lower part of the charging hole, which could not conventionally be treated by mechanical devices.

(7) Use of control grip The coke oven operating device 15 can have a multi-directionally movable control grip attached to the upper part of the jib. With the control gripper it is possible to control gripping movements comparable to hand movements from a control stand, even in inaccessible parts of the hot furnace chamber. In conjunction with optical remote monitoring, it is possible to control work processes such as the removal of damaged refractory bricks, the insertion of new refractory bricks or the insertion of fallen heating plugs in a simple and problem-free manner. Even in areas that are currently difficult to access, shut down the operation of the furnace unit, including adjacent furnaces, lower the heating flame duct temperature, and shield the chamber walls with insulating materials or install mirrors. The chamber walls are repaired so that the interior of the furnace chamber is repaired on the spot. This requires a significant portion of the operating costs. Furthermore, damage to the furnace chamber may occur due to heat rise/fall.

(8) Mobile repair work floor The end jib 46'' can be equipped with a mobile repair work floor that can be operated from the control stand 42. This allows work that conventionally had to be installed on the inspection path 7. There is no need for complicated movement of the floor and protective measures.Furthermore, the jib 45 can also be used as a lift.
